Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The ROBO4 c.283G>A variant is predicted to result in the amino acid substitution p.Ala95Thr. This variant has been reported in an individual with bicuspid aortic valve and thoracic aortic aneurysm (Gould et al 2019. PubMed ID: 30455415). This variant is reported in 0.016% of alleles in individuals of South Asian descent in gnomAD. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
